Title: Method and apparatus for pre-process mounting of file systems in a hierarchical file system environment
Inventor: LYON TOM
IPC: G06F17/30
Filed: 1990-01-12
Abstract: In a computer system having a hierarchical file structure a file system is provided wherein per-process mounting of file systems can be performed. To provide per-process mounting, a temporary directory is created off the current root directory. The file system, starting at the root directory, is then mounted on the temporary directory using an innovative loop-back file system function which results in the file system being duplicated but having the temporary directory as its root directory. A mount can then be performed on the temporary directory without affecting the original file system. A change root directory command is then executed to change the root directory to the temporary directory whereby execution continues on the file system having the temporary directory as its coot.

Title: Telescopable vacuum-cleaner suction pipe
Inventor: CORDES AUGUST
IPC: A47L9/24
Filed: 1990-05-18
Abstract: The inside pipe wall of a telescopic vacuum cleaner suction pipe (10) having an outside pipe (11) and an inside pipe (12) has an impressed catch strip (17) with catch recesses (18), with which strip a catch element (35) interacts. The latter can be disengaged against the restoring force of a spring by means of a holding-down device (30) which is actuated by a sliding handle in the axial direction (x) of the pipe. The annular space (R) formed between a cylindrical end widening (13) of the outside pipe (11) and the inside pipe (12) is filled by a tubular guide element (16) for the holding-down device (30), sliding handle (28), catch element (35) and spring (19). The sliding handle (28) and catch strip (17) are arranged on two diametrically opposite circumferential positions of the vacuum cleaner suction pipe (10). 
<??>A constructional simplification and ease of assembly of the vacuum cleaner suction pipe (10) result from the fact that the holding-down device (30) is arranged directly adjacent to the catch strip (17) inside the annular space (R) between the outside (11) and inside pipe (12), that the guide element (16) maintains tension on one end of a bar spring (19) which is wound at least partially around the guide element (16) inside the annular space (R) and couples the movement of the holding-down device (30) and the sliding handle (28), which penetrates the wall of the end widening (13).

Title: A sintering furnace for the production of a quartz preform

IPC: C03B37/014
Filed: 1990-03-28
Abstract: A furnace used for conducting at least one of the steps of dehydration, fluorine addition and sintering of a porous quartz base material prepared by flame hydrolysis techniques such as vapor-phase axial deposition or outside seeding, which makes it possible to keep completely airtight the joints of a long core tube which cannot be manufactured monolithically, to prevent moisture, oxygen and other impurities contained in the outer atmosphere from intruding inside the core tube, and to prevent corrosive and toxic gases present inside the core tube from leaking outside. The core tube is made of high-purity carbon with its inner wall and/or outer wall being coated with a gas-impermeable coating film. It has a cylindrical form with its axis extending lengthwise, and is divided into several portions along the axis, and the upper and lower edges of each of said divided portions are flattened to provide contact faces, which are sealed with carbon packing interposed therebetween. The core tube has a mechanism for axially pushing it with a uniform force from around its periphery.

Title: Electronic keying of multi-board systems
Inventor: BUNTON WILLIAM P
IPC: H05K1/14
Filed: 1990-12-07
Abstract: ELECTRONIC KEYING OF MULTI-BOARD SYSTEMS     ABSTRACT OF THE DISCLOSURE   A computer system with a number of subsystems or modules on separate circuit boards employs electronic keying to ensure proper configuration of these boards. A power key arrangement associated with a plug-in connector enables a separate power supply for each set of boards. A power supply turn-on signal is routed through auniquely-configured connector path for each board, so the power supply turn-on is inhibited for improper configurations. The uniquely-configured connector path may use either a series or a parallel implementation. The series implementation employs a set of diodes connected for conduction in either of two directions, with the mating connector having its conductor paths connected to match the diode configuration; in this manner, the power supply enable signal can only flow through the series path if the proper board is plugged into a properly-coded slot, in which case the power supply to activate this board is activated through the series path including the diodes. The parallel implementation employs a given number of connector pins to establish the coding for each board, and each pin is either open-circuited or connected to ground; if this coding of the subsystem board is not the same as that of the slot into which it is plugged then the power supply activation signal will be shorted to ground by one or the other of the coded pins.

Title: Overhead support frame assembly for vehicle
Inventor: SIMPSON CLARK
IPC: B66F9/075
Filed: 1991-03-07
Abstract: Abstract of the Disclosure An overhead support frame assembly provides enhanced strength for an attachment for the vehicle or the like, and features minimum obstruction of vision from the driver station.  The frame assembly has a pair of laterally spaced frame units; each including an interconnected tower support plate, overhead extension plate, and upstanding support post.  The base of each tower support plate is attached to the vehicle deck at an approximate 30° angle to the longitudinal axis of the vehicle and slanted forwardly toward the horizontal overhead extension plate at an approximate 10° angle.  The position and angle of the tower support plates provide a 60° unobstructed rear view from the driver station.  Each extension plate is directed to the front of the vehicle and terminates at the upper end of an upstanding support post positioned adjacent to the driver station for secondary support.  Front and rear cross beams extend between the upper ends of the secondary support posts and the tower support plates, respectively,  The frame units and cross beams form the substantially rigid support frame assembly with increased strength in both the compression/tension modes, and especially adapted for mounting overhead cylinders for a forklift attachment.  The arrangement also provides an extended lateral opening for unobstructed side engine access and a substantially unobstructed view to the sides of the vehicle.

Abstract: RADAR ALTIMETER WITH SELF-CALIBRATION FEATURE                 ABSTRACT OF THE DISCLOSURE    A radar altimeter incorporates circuitry for automatically adjusting altitude readings for variations caused by altitude and temperature changes.   Normal target tracking of the radar  is intermittently  interrupted  and  a  calibration  sequence  is interjected.  The current altitude and receiver AGC information at the time of each interruption is temporarily stored and a test is initiated in which a pseudo radar return at that altitude is introduced to the receiver.  The receiver operates on the pseudo return as it would on an actual return.   The transmit power is adjusted automatically for the correct signal level at the tracker.          The resultant altitude measured for the pseudo return is compared to a known test altitude and any difference is stored away as a correction factor to be applied to the altitude reading which had been stored at the time that its operation had been interrupted to perform the calibration test.

Abstract: 2049343 9011666 PCTABS00002 A radio (10) measures and stores (16, 18) the ambient sound (or noise) level of its environment. When a message is received, the current noise (or sound) level is compared to a threshold (56). If the ambient noise level is such that an audible tone may not be heard by the radio user, a silent alert is automatically activated (62) regardless of whether the silent enunciator has been previously selected (enabled) by the radio user. In another aspect of the present invention, if the ambient noise level is such that an audible tone may be inappropriate (i.e., library, courtroom, or certain hospital areas), the silent alert is also automatically activated regardless of whether the silent enunciator is enabled so as not to disturb others.
